[参考译文] MSP430FR2532：在 CAPT_appHandler ()激活时向 LED2添加更长的延迟(30秒)(电容式按钮)

https://e2e.ti.com/support/microcontrollers/msp-low-power-microcontrollers-group/msp430/f/msp-low-power-microcontroller-forum/1323047/msp430fr2532-adding-a-longer-delay-30-seconds-to-led2-while-capt_apphandler-is-active-capacitive-button

TI 论坛、您好！

我正在尝试在以下代码中为 LED2添加更长的延迟。 我尝试了使用__delay_cycles、但最多可以达到15秒左右。 如果我增大该值、则会编译代码、但不起作用。

我尝试实现的是以下目标、

1.用户触摸按钮(进入 CAPT_APPHAN德勒())

2.输出 LED2 (30秒始终开启、无切换)和输出 LED1 (30秒、但快速切换、以降低功耗

3.回到睡眠状态。

下面是我的代码：

// Development main.c for MSP430FR2633, MSP430FR2533, MSP430FR2632, and
// MSP430FR2532.
//
// This starter application initializes the CapTIvate touch library
// for the touch panel specified by CAPT_UserConfig.c/.h via a call to
// CAPT_appStart(), which initializes and calibrates all sensors in the
// application, and starts the CapTIvate interval timer.
//
// Then, the capacitive touch interface is driven by calling the CapTIvate
// application handler, CAPT_appHandler().  The application handler manages
// whether the user interface (UI) is running in full active scan mode, or
// in a low-power wake-on-proximity mode.
//
// The CapTIvate application handler will return true if proximity was
// detected on any of the sensors in the application, which is used here
// to control the state of LED2. LED1 is set while the background loop enters
// the handler, and is cleared when the background loop leaves the handler.
//
// \version 1.83.00.05
// Released on May 15, 2020
